I'm learning SCM ATP. I've created very simple example - 1 planned order (material m1 is prodused) with consumption of 1 raw materail (m4). Stock level for m4 is zero. I've runed heuristics and purchare requisition was created.
In /sapapo/rrp3 for material m1 I manually run ATP for my planned order and my order gets status "Checked and fully Confirmed", which is ok.
Then I reduce the quantity in my purchase requisition and\or putting it delivery cople days later. And performing ATP once again in the same way. I expect that the order should not be confirmed.
But it get's same status - "Checked and fully Confirmed" which looks quite strange. Why that can happen?
I'm using all default customizings for CH ATP group and PP business event (by the way, how can I understand which business event is used when I perfomr ATP on planned order?).
